Martin Kerstein posted a heads up on the Guild Wars 2 forums regarding the upcoming content for November. There are no spoilers ahead, but if you don't want to miss a moment of Guild Wars 2 history in the making, be sure to make room for the scheduled times. The following is taken from that post.

On Friday November 16th at noon PST (20:00 GMT) the weekend will kick off with an Event in Lion's Arch that you don't want to miss. This will trigger events in other parts of Tyria as well.

On Saturday November 17th at noon PST (20:00 GMT), another phase will kick in.Each phase is triggered by a special event, but you will be able to enjoy additional content afterwards even if you cannot make the kick-off time.

There is one exception:The event will culminate in a big Finale on Sunday November 18, make sure you will not miss it. This will be a onetime only event chain that will run multiple hours, and it will kick off at noon PST (20:00 GMT).

There will be plenty of content available to enjoy that will remain permanently in the world as a result of the outcome of this event on Sunday.
